Abstract:

A new method was used to prepare a calix [4] arene-bonded silica stationary phase. The chemically modified calix[4] arene 1 was attached to silica gel via the silane coupling reagent γ-(ethylenediamino ) -propyl-triethoxyl-silane. The resulting bonded phase was characterized by 29 Si and 13C cross polarization/magic angle spinning(CP/MAS) nuclear magnetic resonance(NMR) techniques.

Key words: Silica-bonded calixarenes, Stationary phase, CP/MAS, NMR
